Description

Resource determination method and device
Technical Field
The present invention relates to the field of communications, and in particular, to a resource determination method and apparatus.
Background
Long Term Evolution (LTE) systems employ precoding techniques to improve signal transmission quality or signal transmission rate. In a Frequency Division Duplex (FDD) system, a precoding matrix may be obtained by means of Channel State Information (CSI) fed back by a terminal device. The CSI includes one or more of a Rank Indication (RI), a Precoding Matrix Indication (PMI), a Channel Quality Indication (CQI), a channel state information reference signal resource indication (CRI), and a Reference Signal Received Power (RSRP). Accurate CSI may improve data transmission efficiency and reliability.
In a next generation wireless communication system, an access network device may configure CSI reporting for a terminal device. The CSI reporting may be periodic, aperiodic, or semi-persistent. The periodic CSI reporting refers to performing CSI reporting at a corresponding time according to a period and a time unit offset configured by the access network device. The semi-persistent CSI reporting means that after the access network device performs CSI reporting activation and before CSI reporting deactivation, CSI reporting is performed at a corresponding time by using a period and a time unit offset configured by the access network device. The period and time unit offset may be calculated in units of slots (slots). The periodic CSI report and the semi-persistent CSI report may be carried on a Physical Uplink Control Channel (PUCCH) resource pre-configured for the terminal device by the access network device for transmission. When the access network device configures a PUCCH resource for each periodic CSI report (or semi-persistent CSI report) of the terminal device with Radio Resource Control (RRC) signaling, the CSI report is sent by always using the PUCCH resource until the access network device reallocates the PUCCH resource for the CSI using RRC signaling for the terminal device. Each PUCCH channel occupies certain time domain resources and frequency domain resources. The access network device may configure a plurality of periodic CSI reports or semi-persistent CSI reports for one terminal device, and different periodic CSI reports or semi-persistent CSI reports may have different periodic or time unit offsets. As shown in fig. 1, the access network device configures two different periodic CSI reports for the terminal device, such as CSI1 and CSI2 in the figure, where a reporting period of CSI1 is T1, and a reporting period of CSI2 is T2.
In addition to periodic CSI, the acknowledgement feedback for downlink data scheduling is also carried on PUCCH. The acknowledgement feedback is also referred to as hybrid automatic repeat request-acknowledgement (HARQ-ACK) information, and is also referred to as acknowledgement/negative acknowledgement (ACK/NACK) information. The acknowledgement feedback includes an ACK or NACK. The response feedback is used to inform the access network device whether the data scheduled in the downlink at a time is received correctly by itself. If the terminal device feeds back ACK, it indicates that the downlink scheduled data is correctly received, and if the terminal device feeds back NACK, it indicates that the downlink scheduled data is not correctly received. The access network equipment can judge whether the data packet needs to be retransmitted according to the ACK/NACK fed back by the terminal equipment. The response mechanism is an important mechanism for ensuring the scheduling reliability of the downlink data.
Unlike the periodic CSI, a PUCCH resource occupied by ACK/NACK may be dynamically selected from a plurality of PUCCH resources defined or configured in advance through Downlink Control Information (DCI). Specifically, the access network device configures N PUCCH resources for the terminal device through RRC signaling, where N is a positive integer. Then, when one DCI schedules a downlink shared channel (PDSCH) transmission, the DCI further indicates one resource from N preconfigured PUCCH resources, which is used for carrying ACK/NACK that needs to be fed back for the PDSCH transmission.
By configuring appropriate period and time unit offsets, multiple pieces of periodic CSI do not normally occur to be transmitted in the same slot.
However, at some time, it still cannot be avoided that multiple periodic CSI and/or ACK/NACK messages need to be transmitted in the same slot. When a plurality of PUCCH resources carrying the information collide, the UE cannot directly transmit the information according to the pre-configured resource or the resource indicated by the DCI, otherwise, the transmission performance of the information may be degraded. The collision of the different PUCCH resources may be that the PUCCH resources occupy at least one same OFDM symbol. Therefore, there is a need to provide a resource determination mechanism, which can provide a feasible scheme for collision of multiple PUCCH resources of periodic CSI and/or ACK/NACK.
Disclosure of Invention
Embodiments of the present invention provide a method and an apparatus for determining resources, so that a plurality of pieces of uplink control information need to be sent in the same time unit.
In a first aspect, a resource determination method is provided. The method comprises the following steps: determining that at least two Physical Uplink Control Channel (PUCCH) resources collide in a time unit n, wherein n is an integer, and the at least two PUCCH resources comprise a first resource configured for first Uplink Control Information (UCI) and a second resource configured for second UCI; determining the first resource and a third resource in the time unit n, where the third resource is one of M PUCCH resources, the first resource and the third resource do not include the same orthogonal frequency division multiplexing OFDM symbol in a time domain, the M is a positive integer greater than or equal to 1, the first resource is used to carry part or all of the first UCI, and the third resource is used to carry part or all of the second UCI. That is, the first resource is configured to carry a third UCI, where the third UCI is part or all of the first UCI, the third resource is configured to carry a fourth UCI, and the fourth UCI is part or all of the second UCI.
The steps may be executed by the network device or a chip in the network device, or may be executed by the terminal device or a chip in the terminal device.
In a second aspect, a wireless device is provided. The apparatus includes a processor and a memory coupled to the processor. The processor is configured to determine that at least two Physical Uplink Control Channel (PUCCH) resources collide within a time unit n, where n is an integer, and the at least two PUCCH resources include a first resource configured for first Uplink Control Information (UCI) and a second resource configured for second UCI. The processor is further configured to determine the first resource and a third resource in the time unit n, where the third resource is one of M PUCCH resources, the first resource and the third resource do not include the same orthogonal frequency division multiplexing OFDM symbol in a time domain, M is a positive integer greater than or equal to 1, the first resource is configured to carry a third UCI, the third UCI is part or all of the first UCI, the third resource is configured to carry a fourth UCI, and the fourth UCI is part or all of the second UCI.
In the above scheme, since the first resource and the third resource in the time unit n are determined when at least two PUCCH resources collide, where the third resource and the first resource do not include the same OFDM symbol in the time domain, that is, the first resource for carrying part or all of the first UCI and the third resource for carrying part or all of the second UCI are Time Division Multiplexing (TDM), the above scheme provides a possibility for transmitting part or all of the first UCI and part or all of the second UCI in a TDM manner. Further, since part or all of the first UCI is still carried on the first resource configured for the first UCI, it may be avoided that the transmission reliability of the UCI transmitted on the first resource and the feedback delay are affected by PUCCH resource collision.
In the above scheme, each PUCCH resource may be uniquely determined by one or more parameters. For example, one PUCCH resource can be uniquely determined by defining an occupied OFDM symbol index, an occupied Resource Block (RB) index, a PUCCH format, and the like. It should be noted that the parameters for uniquely determining one PUCCH resource may further include other parameters, such as an orthogonal code superposition (OCC) and/or a maximum channel coding rate (tcc).
The access network device may also configure a PUCCH resource for the terminal device through higher layer signaling, for example, Radio Resource Control (RRC) signaling. Optionally, one or more of the above parameters may be included in higher layer signaling to implement configuring the one PUCCH resource. Here, "N PUCCH resources" correspond to the configuration of N PUCCH resources, and the configuration of each PUCCH resource includes all or part of the above parameters. The above parameters corresponding to different PUCCH resource configurations may be partially or entirely different.
Optionally, all or part of the first UCI and all or part of the second UCI are sent on the first resource and the third resource within the time unit n, where part or all of the first UCI is carried on the first resource, and part or all of the second UCI is carried on the third resource. That is, the third UCI and the fourth UCI are transmitted within the time unit n, wherein the third UCI is carried on the first resource and the fourth UCI is carried on the third resource. This step may be performed by the terminal device or a chip in the terminal device.
Correspondingly, all or part of the first UCI and all or part of the second UCI are received on the first resource and a third resource within the time unit n, wherein part or all of the first UCI is carried on the first resource, and part or all of the second UCI is carried on the third resource. Receiving the third UCI and the fourth UCI within the time unit n, wherein the third UCI is carried on the first resource, and the fourth UCI is carried on the third resource. This step may be performed by the network device or a chip in the network device.
Optionally, the apparatus further comprises a transceiver. The transceiver is configured to transmit the third UCI and a fourth UCI in the time unit n, where the third UCI is carried on the first resource and the fourth UCI is carried on the third resource.
Optionally, the apparatus further comprises a transceiver. The transceiver is configured to receive the third UCI and the fourth UCI within the time unit n, where the third UCI is carried on the first resource and the fourth UCI is carried on the third resource.
Optionally, the number of OFDM symbols occupied by at least one of the third resource and the first resource in the time domain is less than or equal to 2. That is, at least one of the third resource and the first resource corresponds to a short PUCCH.
For example, the number of OFDM symbols occupied by one of the third resource and the first resource in the time domain is greater than 2, and the number of OFDM symbols occupied by the other of the third resource and the first resource in the time domain is less than or equal to 2. Or, that is, the number of OFDM symbols occupied by the third resource and the first resource in the time domain is less than or equal to 2.
Optionally, M is greater than or equal to 2, the third resource is one PUCCH resource with the smallest number of occupied resource elements RE or resource blocks RB among M1 PUCCH resources in the M PUCCH resources, where each resource in the M1 PUCCH resources satisfies that a maximum number of bits that can be carried is greater than or equal to a sum of all bits of the second UCI and a Cyclic Redundancy Check (CRC) bit number, and each resource in the M1 PUCCH resources and the first resource do not include the same OFDM symbol in a time domain. Therefore, on the premise that the M1 PUCCH resources all satisfy TDM with the first resource, the selected third resource satisfies the requirement of being able to accommodate all the second UCI bits and CRC bits, and occupies the PUCCH resource whose number of REs or RBs is the minimum among the M1 PUCCH resources, thereby avoiding unnecessary resource waste.
Optionally, the maximum number of bits that can be carried by one PUCCH resource is based on MRBNscNsymbQmrmaxObtain, for example, a maximum number of bits of MRBNscNsymbQmrmax. Wherein M isRBNumber of RBs occupied in frequency domain for the PUCCH resource, NscNumber of subcarriers contained for each RB, NsymbThe number of OFDM symbols, Q, occupied by the PUCCH resource in the time domainmThe modulation order used on the PUCCH resource may be, for example, a modulation order used when CSI is transmitted on the PUCCH resource, rmaxAnd coding the code rate for the maximum channel allowed by the PUCCH resource. These parameters may be configured by the access network device to the terminal device. For example, the access network device is configured for the terminal device for one PUCCH resource.
Optionally, the third resource is a PUCCH resource with the largest number of REs included in M2 PUCCH resources; or, the third resource is a PUCCH resource with the largest number of RBs included in the M2 PUCCH resources; or, the third resource is a PUCCH resource with a maximum number of bits that can be carried in M2 PUCCH resources, where the M2 PUCCH resources are ones of the M PUCCH resources, each of the M2 PUCCH resources and the first resource do not include a same OFDM symbol in a time domain, and M2 is a positive integer. In the scheme, all or part of the second UCI is carried by selecting one PUCCH resource occupying the maximum number of RBs or REs or capable of carrying the maximum number of bits, so that information in the second UCI is sent as much as possible, and the system performance can be improved.
The principle of dropping may be predefined when a part of the second UCI is not transmitted and may need to be dropped when another part of the second UCI is carried on the third resource. For example, the fourth UCI may be determined from the second UCI according to a priority of CSI included in the second UCI. The same is true for the case where part of the first UCI is carried on the first resource.
Optionally, the determining the third resource in the time unit n includes:
determining M2 PUCCH resources of the M PUCCH resources, wherein each of the M2 PUCCH resources and the first resource do not include the same OFDM symbol in a time domain, and M2 is a positive integer; and
determining a resource, in which the maximum number of bits that can be carried by the M2 PUCCH resources is greater than or equal to the sum of all the number of bits of the second UCI and the number of Cyclic Redundancy Check (CRC) bits, as the third resource.
And determining the PUCCH resource as a third resource if M2-1 PUCCH resources exist in the M PUCCH resources, and the PUCCH resource can accommodate all second UCI bits and CRC bits.
Optionally, the determining the third resource in the time unit n includes:
determining M2 PUCCH resources of the M PUCCH resources, wherein each of the M2 PUCCH resources and the first resource do not include the same OFDM symbol in a time domain, and M2 is a positive integer;
determining that no resource exists in the M2 PUCCH resources, wherein the maximum bit number capable of being carried is greater than or equal to the sum of all bit numbers of the second UCI and the CRC bit number;
determining the third resource to be a resource satisfying the following condition among the M2 PUCCH resources:
the PUCCH resources occupying the largest number of REs in the M2 PUCCH resources; alternatively, the first and second electrodes may be,
the PUCCH resource occupying the largest number of RBs in the M2 PUCCH resources; alternatively, the first and second electrodes may be,
and the PUCCH resource with the maximum number of bits capable of being carried in the M2 PUCCH resources.
In this scheme, if M2 PUCCH resources exist in the M PUCCH resources, which satisfy TDM with the first resource, but there is no resource that can accommodate all the second UCI bits and CRC bits in the M2 PUCCH resources, the PUCCH resource with the largest number of REs or RBs occupied in the M2 resources or the largest number of bits that can be carried is determined as the third resource. The third resource carries part of the second UCI, so that as much information as possible in the second UCI is transmitted, and system performance can be improved.
Optionally, the determining that at least two physical uplink control channel PUCCH resources collide includes:
determining that at least three PUCCH resources are included in the time unit n. That is, it is equivalent to determining that at least three PUCCH resources are included in the time unit n when the collision of the at least two PUCCH resources is determined.
When it is determined that at least three PUCCH resources are included in one time unit, the at least three PUCCH resources are configured for UCI required to be transmitted, that is, at least three UCI are required to be transmitted in the same time unit, PUCCH collision is considered regardless of whether at least one identical OFDM symbol is occupied between the at least three PUCCH resources. Therefore, the judgment process can be simplified, a unified processing frame is designed, and the design principle is simplified.
Optionally, the determining that the time unit n includes at least three PUCCH resources includes:
determining whether there is periodic CSI to be transmitted and PUCCH resources configured for the periodic CSI to be transmitted in time unit n according to configuration information (which may include information of PUCCH resources used and one or more of a period and a time unit offset of the periodic CSI report) reported by the periodic CSI;
determining whether there is a PUCCH resource which needs to send ACK/NACK and configures and indicates the ACK/NACK which needs to be sent in a time unit n;
in addition, whether the SR to be transmitted and the PUCCH resource configured for the SR to be transmitted exist in the time unit n is determined according to the resource configuration information of the SR, and the period and time unit offset reported by the SR.
According to the above procedure, the PUCCH resources that should be originally transmitted in time unit n, that is, the number of PUCCH resources included in time unit n can be determined.
It should be noted that, when determining the number of PUCCH resources included in time unit n, the terminal device may determine the number according to configuration information sent by the access network device. For example, it is determined whether there is periodic CSI to be transmitted in time unit n and PUCCH resources configured for the periodic CSI to be transmitted are determined according to the resource configuration information reported by the periodic CSI. And the terminal equipment determines whether the ACK/NACK needing to be sent exists in the time unit n or not according to the DCI sent by the access network equipment and the PUCCH resource configured for the ACK/NACK needing to be sent. The terminal device determines whether there are SR to be transmitted and PUCCH resource configured for SR to be transmitted in time unit n according to resource configuration information of SR transmitted by the access network device, and cycle and time unit offset reported by SR.
The access network device can determine the number of PUCCH resources included in the time unit n according to its configuration information.
Optionally, the determining that at least two physical uplink control channel PUCCH resources collide includes:
determining that the time unit n comprises two PUCCH resources, wherein the number of occupied OFDM symbols of the two PUCCH resources is greater than or equal to 4; alternatively, the first and second electrodes may be,
and determining that the time unit n comprises two PUCCH resources, and the two PUCCH resources occupy at least one same OFDM symbol.
Transmitting multiple PUCCHs on the same OFDM symbol in a Frequency Division Multiplexing (FDM) manner may result in a large Peak to average power ratio (PAPR) of a signal transmitted by a terminal device, resulting in a low actual transmission power of the signal, and further resulting in a reduction in PUCCH transmission performance. Therefore, the scheme can avoid sending a plurality of PUCCHs by the FDM method, thereby avoiding the reduction of PUCCH transmission performance.
It should be noted that, in the embodiment of the present invention, the time unit n includes K PUCCH resources, which means that there is UCI to be transmitted in the time unit n determined according to the configuration information and/or DCI, and there are K PUCCH resources configured for the UCI to be transmitted. K is at least two specific values.
Optionally, the first UCI and the second UCI are of different types, wherein,
the type of the first UCI comprises one or more of hybrid automatic repeat request-acknowledgement HARQ-ACK information, channel state information CSI and scheduling request SR, and the type of the second UCI comprises one or more of hybrid automatic repeat request-acknowledgement HARQ-ACK information, channel state information CSI and scheduling request SR.
For example, the type of the first UCI may be HARQ-ACK, or SR, or CSI, or HARQ-ACK and SR, or HARQ-ACK and CSI, or SR and CSI, or HARQ-ACK, SR, and CSI. Other combinations are not excluded. Further optionally, the first UCI at least includes HARQ-ACK and/or SR.
The type of the second UCI may be HARQ-ACK, or SR, or CSI, or HARQ-ACK and SR, or HARQ-ACK and CSI, or SR and CSI, or HARQ-ACK, SR, and CSI. Other combinations are not excluded. Further optionally, the second UCI at least includes CSI.
But the type of the first UCI and the type of the second UCI are different.
The type of the UCI is determined according to UCI content, and the UCI content comprises one or more of hybrid automatic repeat request-acknowledgement (HARQ-ACK) information, Channel State Information (CSI) and Scheduling Request (SR).
For example, the UCI content may be HARQ-ACK, or SR, or CSI, or HARQ-ACK and SR, or HARQ-ACK and CSI, or SR and CSI, or HARQ-ACK, SR, and CSI. Others are not excluded. Optionally, the determining the first resource includes:
determining that the at least two PUCCH resources comprise at least one resource configured for HARQ-ACK information, wherein the one resource is the first resource, and the first UCI comprises the HARQ-ACK information.
Considering that the priority of the HARQ-ACK information is often higher, the HARQ-ACK information is sent through PUCCH resources originally configured for the HARQ-ACK information and is not sent on one PUCCH resource by being multiplexed with other UCIs, so that the reduction of the HARQ-ACK transmission performance caused by multiplexing the UCIs can be reduced, or the phenomenon that the HARQ-ACK and the other UCIs are multiplexed to introduce extra HARQ-ACK feedback time delay is avoided.
Optionally, the determining the first resource includes:
determining that the at least two PUCCH resources comprise one resource configured for first CSI and one resource configured for second CSI, wherein the first resource is the one resource configured for the first CSI, the first UCI comprises the first CSI, and the second UCI comprises the second CSI.
Further optionally, the at least two PUCCH resources further include at least one resource configured for HARQ-ACK information, and the second UCI further includes the HARQ-ACK information.
Optionally, the transmission parameter of the first CSI is greater than the transmission parameter of the second CSI, where the transmission parameter includes one or more of a reference bit number before coding, a reference bit number after coding, a priority of the CSI, and a configuration index of the CSI; or the resource parameter of the resource carrying the first CSI is greater than the resource parameter of the resource carrying the second CSI, wherein the resource parameters include: one or more of the number of RBs occupied by the PUCCH resources, the number of REs occupied by the PUCCH resources, the number of OFDM symbols occupied by the PUCCH resources, and the maximum number of bits that can be carried by the PUCCH resources.
Optionally, the reference bit number of the UCI may be an actual bit number of the UCI, or a maximum bit number of the UCI under a certain condition, or a bit number of the UCI under a certain parameter value. For example, if the UCI is CSI, the reference bit number of the CSI may be the maximum bit number of the CSI under all values of CRI/RI, or the reference bit number of the CSI is the CSI bit number under a certain predefined CRI/RI value, or the maximum bit number of the CSI within a certain value range of other measurement parameters. Others are not excluded.

For simplicity, communication of one network device 202 (e.g., an access network device) and two wireless devices 204 (e.g., terminal devices) is shown in fig. 2. In general, a wireless communication system may include any number of network devices as well as terminal devices.

The access network device may include various forms of macro Base Stations (BSs), micro base stations (also referred to as small stations), relay stations, or access points, etc. In systems using different radio access technologies, names of devices having radio access functions may be different, for example, in an LTE system, the devices are called evolved node bs (enbs) or enodebs, and in a third generation (3G) system, the devices are called node bs (node bs). For convenience of description, in this application, it is referred to as an access network device, sometimes referred to as a base station.

Further, a schematic diagram of a possible structure of the access network device 202 may be as shown in fig. 3. The access network device 202 is capable of performing the methods provided by the embodiments of the present invention. The access network device 202 may include: a controller or processor 301 (processor 301 is illustrated below) and a transceiver 302. Controller/processor 301 is also sometimes referred to as a modem processor (modem processor). The modem processor may include a baseband processor (BBP) (not shown) that processes the digitized received signal to extract the information or data bits conveyed in the signal. As such, the BBP is typically implemented in one or more Digital Signal Processors (DSPs) within the modem processor or as a separate Integrated Circuit (IC) as needed or desired.
The transceiver 302 may be used to support the transceiving of information between the access network device 202 and the terminal device, as well as to support the radio communication between the terminal devices. The processor 301 may also be used to perform the functions of various terminal devices communicating with other network devices. In the uplink, uplink signals from the terminal device are received via the antenna, demodulated by the transceiver 302, and further processed by the processor 301 to recover traffic data and/or signaling information sent by the terminal device. On the downlink, traffic data and/or signaling messages are processed by the terminal device and modulated by transceiver 302 to generate a downlink signal, which is transmitted via the antenna to the terminal device. The access network device 202 may also include a memory 303 that may be used to store program codes and/or data for the access network device 202. The transceiver 302 may include separate receiver and transmitter circuits or may be the same circuit that performs the transceiving function.

The bus may include an address bus, a data bus, and a control bus, among others.
Fig. 4 is a schematic diagram of a possible structure of a terminal device in the wireless communication system. The terminal equipment can execute the method provided by the embodiment of the invention. The terminal device may be either of the two terminal devices 204. The terminal device includes a transceiver 401, an application processor (application processor)402, a memory 403, and a modem processor (modem processor) 404.
The transceiver 401 may condition (e.g., analog convert, filter, amplify, and upconvert, etc.) the output samples and generate an uplink signal, which is transmitted via an antenna to the base station as described in the above-described embodiments. On the downlink, the antenna receives a downlink signal transmitted by the access network device. The transceiver 401 may condition (e.g., filter, amplify, downconvert, digitize, etc.) the received signal from the antenna and provide input samples.
Modem processor 404, sometimes referred to as a controller or processor, may include a baseband processor (BBP) (not shown) that processes the digitized received signal to extract the information or data bits conveyed in the signal. The BBP is typically implemented in one or more numbers within modem processor 404 or as separate Integrated Circuits (ICs) as needed or desired.
In one design, a modem processor (modem processor)404 may include an encoder 4041, a modulator 4042, a decoder 4043, and a demodulator 4044. The encoder 4041 is used to encode a signal to be transmitted. For example, encoder 4041 may be configured to receive traffic data and/or signaling messages to be transmitted on the uplink and to process (e.g., format, encode, interleave, etc.) the traffic data and signaling messages. The modulator 4042 is used to modulate the output signal of the encoder 4041. For example, the modulator may process symbol mapping and/or modulation, etc., of the encoder's output signals (data and/or signaling) and provide output samples. The demodulator 3044 is configured to perform demodulation processing on the input signal. For example, demodulator 4044 processes the input samples and provides symbol estimates. The decoder 4043 is used to decode the demodulated input signal. For example, the decoder 4043 deinterleaves and/or decodes the demodulated input signal, and outputs a decoded signal (data and/or signaling). The encoder 4041, modulator 4042, demodulator 4044, and decoder 4043 may be implemented by a combined modem processor 404. These elements are processed according to the radio access technology employed by the radio access network.
Modem processor 404 receives digitized data, which may represent voice, data, or control information, from application processor 402 and processes the digitized data for transmission. The modem processor may support one or more of various wireless communication protocols of various communication systems, such as LTE, new air interface, Universal Mobile Telecommunications System (UMTS), High Speed Packet Access (HSPA), and so on. Optionally, one or more memories may also be included in modem processor 404.
Alternatively, the modem processor 404 and the application processor 402 may be integrated in a single processor chip.
The memory 403 is used for storing program code (also sometimes referred to as programs, instructions, software, etc.) and/or data for supporting the communication of the terminal devices.
It should be noted that the memory 303 or the memory 403 may include one or more storage units, for example, a storage unit inside the processor 301 or the modem processor 404 or the application processor 402 for storing program codes, or an external storage unit independent from the processor 301 or the modem processor 404 or the application processor 402, or a component including a storage unit inside the processor 301 or the modem processor 404 or the application processor 402 and an external storage unit independent from the processor 301 or the modem processor 404 or the application processor 402.
Processor 301 and modem processor 404 may be the same type of processor or may be different types of processors. For example, the present invention may be implemented in a Central Processing Unit (CPU), a general purpose Processor, a Digital Signal Processor (DSP), an Application-Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other Programmable logic device, a transistor logic device, a hardware component, other Integrated circuits, or any combination thereof. The processor 301 and modem processor 404 may implement or execute the various illustrative logical blocks, modules, and circuits described in connection with the disclosure of embodiments of the invention. The processor may also be a combination of devices implementing computing functionality, including for example one or more microprocessor combinations, DSP and microprocessor combinations or system-on-a-chip (SOC) or the like.
Those of skill in the art would appreciate that the various illustrative logical blocks, modules, circuits, and algorithms described in connection with the aspects disclosed herein may be implemented as electronic hardware, instructions stored in a memory or another computer-readable medium and executed by a processor or other processing device, or combinations of both. As an example, the apparatus described herein may be used in any circuit, hardware component, IC, or IC chip. The memory disclosed herein may be any type and size of memory and may be configured to store any type of information as desired. To clearly illustrate this interchangeability, various illustrative components, blocks, modules, circuits, and steps have been described above generally in terms of their functionality. How such functionality is implemented depends upon the particular application, design choices, and/or design constraints imposed on the overall system. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present invention.
It should be noted that the time unit in the embodiment of the present invention may be a time slot, or may be a subframe, or may be a time-frequency resource on N Orthogonal Frequency Division Multiplexing (OFDM) symbols.
When at least two PUCCH resources configured for periodic CSI and/or semi-persistent CSI and/or HARQ-ACK information in a certain time unit occupy at least one same OFDM symbol, a PUCCH resource collision problem may occur.
Fig. 5 is a diagram illustrating a PUCCH resource collision. In this example, the time unit is a slot (slot). It can be seen that, in the slot, there is a partially identical time domain resource for PUCCH resource 1 for transmitting CSI1 and PUCCH resource for transmitting CSI 2.
In addition to collision between PUCCH resources for periodic CSI, collision between PUCCH resources for ACK/NACK and PUCCH resources for periodic CSI may also occur.
Fig. 6 is a diagram illustrating another PUCCH resource collision situation. In this example, the time unit is a slot (slot). It can be seen that in this slot 1, the DCI schedules the PDSCH. And determining that the PUCCH resource for ACK/NACK feedback of the PDSCH is PUCCH resource 3 in slot 2 according to the number of ACK/NACK bits corresponding to the PDSCH and the DCI. According to the configuration of the periodic CSI, CSI1 and CSI2 need to be fed back on PUCCH resource 1 and PUCCH resource 2 in slot 2, respectively. At this time, PUCCH resource 3 for feeding back ACK/NACK collides with PUCCH resource 1 for feeding back CSI 1. In addition, since only at most two PUCCHs are currently supported for transmission/reception in one slot, the embodiment of the present invention considers that 3 PUCCH resources need to be transmitted or received in one slot as shown in fig. 6 as a case of collision.
Although colliding PUCCHs may occupy different subcarriers, transmitting two UCIs through two FDM PUCCH resources on the same OFDM symbol may result in impairment of UCI transmission performance. This is because transmitting a plurality of PUCCHs in FDM manner on the same OFDM symbol leads to a large PAPR of a signal transmitted by the terminal device, and thus leads to a low actual transmission power of the signal, which in turn leads to a reduction in UCI transmission performance. Therefore, the terminal device is not supported in the next generation communication system to transmit UCI through PUCCH resources occupying at least one same OFDM symbol in an FDM manner. Therefore, the embodiments of the present invention provide a resource determining method and apparatus, which can implement sending UCI in a time unit in a TDM manner when at least two configured PUCCH resources collide.
Further, the next generation communication system defines two PUCCH formats: long pucch (long pucch) and short pucch (short pucch). One long PUCCH resource may occupy 4-14 OFDM symbols, and one short PUCCH resource may occupy 1-2 OFDM symbols.
At present, a terminal device can send UCI through two PUCCH resources in a TDM manner at most in one time unit, where the two PUCCH resources may be a resource corresponding to a short PUCCH and a resource corresponding to a long PUCCH; or the two PUCCH resources may be resources corresponding to two short PUCCH. The case where both are long PUCCH is not supported.
When the PUCCH resources aiming at the CSI with a plurality of periods collide, the next generation wireless communication system defines the following mechanism to solve the problem of PUCCH collision:
1. the access network device configures one or two PUCCH resources for the terminal device, such PUCCH being referred to herein as a multi-CSI PUCCH (multi-CSI PUCCH) resource;
2. when the PUCCH resources which conflict with each other do not occur in a slot, the terminal device sends CSI on the PUCCH resource corresponding to each CSI, where the PUCCH resources which conflict with each other and have the periodic CSI are defined as: two PUCCH resources configured for two periodic CSI occupy at least one same OFDM symbol.
3. When two or more conflicted PUCCH resources appear in a slot, the terminal equipment selects one multi-CSI PUCCH resource from the multi-CSI PUCCH resources according to a predefined rule for bearing UCI borne by the conflicted PUCCH resources.
Since the access network device can predict whether collision of multiple PUCCH resources will occur within one slot, the access network device may determine one multi-CSI PUCCH resource according to the above rule and detect UCI on the multi-CSI PUCCH resource.
However, in the prior art, when N PUCCH resources collide, N PUCCH resources originally configured are no longer used, and multi-CSI PUCCH resources are used to transmit UCI corresponding to the N PUCCH resources. The method causes waste of N PUCCHs, and particularly causes serious PUCCH resource waste when the numerical value of N is large. To solve the problem, the embodiment of the present invention provides a method, which can reduce waste of originally configured PUCCH resources as much as possible in the case of solving PUCCH resource collision.
For the case of PUCCH resource collision of CSI and ACK/NACK, the prior art solves the problem of PUCCH resource collision according to the following mechanism:
1. the terminal equipment selects the K PUCCH resource sets S according to the total bit number of CSI and ACK/NACK needing to be sent in the time unit i1,…,SKTo determine a set Sj；
2. According to the DCI, the terminal equipment determines a set SjPUCCH resource x in (2).
3. And the terminal equipment transmits the ACK/NACK and the CSI by using the selected PUCCH resource x.
It can be seen that the prior art puts all CSI and ACK/NACK in the same PUCCH resource for transmission. When the number of bits of CSI is large, or when a plurality of PUCCH resources of CSI collide with PUCCH resources of ACK/NACK, since the number of bits of CSI is often large, when the time-frequency resources occupied by the finally selected PUCCH resources are small, the channel coding rate of ACK/NACK is high when CSI and ACK/NACK are transmitted together, and thus the transmission reliability of ACK/NACK is affected. To solve this problem, embodiments of the present invention provide a method, which can reduce the impact on the performance of ACK/NACK as much as possible when PUCCH resource collision is resolved.
The terms used in the embodiments of the present invention will be described below.
At least two PUCCH resources: may be a periodic resource configured for CSI or may be a resource for feeding back ACK/NACK. Each PUCCH resource may be uniquely determined by one or more parameters. For example, one PUCCH resource can be uniquely determined by defining an occupied OFDM symbol index, an occupied Resource Block (RB) index, a PUCCH format, and the like. It should be noted that the parameters for uniquely determining one PUCCH resource may further include other parameters, such as an orthogonal code superposition (OCC) and/or a maximum channel coding rate (tcc).
The "N PUCCH resources" described herein may correspond to a configuration of N PUCCH resources, each including all or part of the above resource parameters. The resource parameters corresponding to the configurations of different PUCCH resources may be partially or entirely different. Each PUCCH resource may be uniquely determined by one or more resource parameters. For example, the resource parameter may be one or more of an OFDM symbol index occupied by the PUCCH resource, a Resource Block (RB) index occupied by the PUCCH resource, a PUCCH format, and the like. The resource parameters may also include an orthogonal code superposition (OCC) and/or a maximum channel coding rate, etc.
The at least two PUCCH resources include a first PUCCH resource (first resource for short) configured for a first UCI and a second PUCCH resource (second resource for short) configured for a second UCI.
The first UCI may be ACK/NACK, or may be ACK/NACK and Scheduling Request (SR), or may be first CSI, or may be ACK/NACK and first CSI. Other cases do not exclude that the first CSI may be one or more of CRI, CQI, PMI, RI, and RSRP. Further, the first CSI may be periodic CSI (periodic CSI) or semi-persistent CSI (semi-persistent CSI).
The second UCI may be the second CSI. The second CSI may be one or more of CRI, CQI, PMI, RI, and RSRP. Further, the second CSI may be periodic CSI (periodic CSI) or semi-persistent CSI (semi-persistent CSI).
The second UCI may also be second CSI and SR, or second CSI and NACK/ACK, or second CSI, ACK/NACK and SR. Other situations are not excluded.
The access network device may send the information of the periodic resource configured by the CSI to the terminal device through signaling. The signaling used may be RRC high layer signaling, or Media Access Control element (MAC CE) signaling. The resource for feeding back ACK/NACK can be determined according to the configuration of higher layer signaling and/or MAC CE signaling and the indication of DCI, for example, X resources are configured by the higher layer signaling, and the DCI passes through
Figure BDA0001580157200000131
Each bit determines which of the X resources is the resource used this time.
M PUCCH resources: the one or more PUCCH resources may be configured for the access network device to signal to the terminal device, e.g., may be multi-CSI PUCCH resources as described above. The signaling used may be RRC high layer signaling, or MAC CE signaling.
It should be noted that the embodiment of the present invention does not limit the relationship between the M PUCCH resources and the at least two PUCCH resources, for example, the M PUCCH resources and the at least two PUCCH resources may be completely different, or the M PUCCH resources and the at least two PUCCH resources may include partially identical frequency domain resources, or the M PUCCH resources and the at least two PUCCH resources may include partially identical time domain resources. Or, the M PUCCH resources include at least two PUCCH resources. The unit of the frequency domain resource may be a subcarrier or a resource block RB (composed of a plurality of consecutive subcarriers), and the unit of the time domain resource may be an OFDM symbol.
Time unit: may be a slot, or a subframe, or a plurality of OFDM symbols, etc.
The OFDM symbol is the minimum unit of time domain resources.
In the embodiment of the present invention, when at least two PUCCH resources collide in a time unit n, a part or all of a first UCI that should be originally carried on a first resource and a part or all of a second UCI that should be originally carried on a second resource are respectively carried on the first resource and a third resource in the time unit n and transmitted, where the third resource is one of M PUCCH resources, the first resource and the third resource do not include the same OFDM symbol in a time domain, and M is a positive integer greater than or equal to 1.
In the above scheme, since the first resource and the third resource in the time unit n are determined when at least two PUCCH resources collide, where the third resource and the first resource do not include the same OFDM symbol in the time domain, that is, the first resource for carrying part or all of the first UCI and the third resource for carrying part or all of the second UCI are time-divided, the above scheme provides a possibility for transmitting part or all of the first UCI and part or all of the second UCI in a TDM manner in one time unit. Further, since part or all of the first UCI is still carried on the first resource configured for the first UCI, it may be avoided that the transmission reliability of the UCI transmitted on the first resource and the feedback delay are affected by PUCCH resource collision.
In contrast, in the prior art, when at least two PUCCH resources collide, all UCI to be transmitted is put into one reselected PUCCH resource for transmission, and the reselected PUCCH resource is also preconfigured and is different from the PUCCH resource of the colliding PUCCH resource. Since the number of OFDM symbols occupied by the reselected PUCCH resource may be different from the number of OFDM symbols occupied by the first resource, and the number of first OFDM symbols occupied by the reselected PUCCH resource may also be different from the number of OFDM symbols occupied by the first resource, the feedback delay of UCI on the first resource may be affected by using the reselected PUCCH resource to transmit UCI on the first resource. If the UCI originally required to be carried by the first resource is ACK/NACK and the ACK/NACK required to be fed back at this time needs fast feedback (for example, ACK/NACK for low latency service feedback), if the first OFDM symbol occupied by the reselected PUCCH resource is later than the first OFDM symbol of the first resource, then transmitting the ACK/NACK using the reselected PUCCH resource will introduce additional feedback latency. In addition, if all the UCIs that need to be carried by the reselected PUCCH resource include CSI and ACK/NACK, and the bit number of CSI is often large, when the time-frequency resource occupied by the reselected PUCCH resource is small, the CSI and ACK/NACK are transmitted together, which may result in a high channel coding rate of ACK/NACK, and may result in the transmission reliability of ACK/NACK being affected.
In an alternative, M is greater than or equal to 2, the third resource is one PUCCH resource with the smallest number of occupied REs or RBs from among M1 PUCCH resources, where the M1 PUCCH resources are resources from among the M PUCCH resources, each resource from among the M1 PUCCH resources satisfies that the maximum number of bits that can be carried is greater than or equal to the sum of the total number of bits of the second UCI and the number of cyclic redundancy check bits, each resource from among the M1 PUCCH resources and the first resource do not include the same OFDM symbol in the time domain, and M1 is an integer greater than or equal to 2.
It should be noted that, in this embodiment of the present invention, the first resource and the third resource do not include the same OFDM symbol in the time domain, which may also be referred to as that the first resource and the third resource do not overlap in the time domain.
In the above alternative, when M1 PUCCH resources all satisfy the TDM condition of the first resource, the selected third resource satisfies the requirement of being able to accommodate all the second UCI bits and CRC bits, and occupies the PUCCH resource whose number of REs or RBs is the minimum number of the M1 PUCCH resources, thereby avoiding the waste of unnecessary resources.
Further, the maximum number of bits that the PUCCH resource can carry may be based on MRBNscNsymbQmrmaxAnd (4) determining. Wherein M isRBNumber of RBs occupied in frequency domain for the PUCCH resource, NscNumber of subcarriers contained for each RB, NsymbThe number of OFDM symbols, Q, occupied by the PUCCH resource in the time domainmThe modulation order used on the PUCCH resource may be, for example, a modulation order used when CSI is transmitted on the PUCCH resource, rmaxAnd coding the code rate for the maximum channel allowed by the PUCCH resource. These parameters may be configured by the access network device to the terminal device. For example, the access network device is configured for the terminal device for one PUCCH resource. Optionally, the maximum number of bits that can be carried by the PUCCH resource may be MRBNscNsymbQmrmax。
In another alternative, the third resource is a PUCCH resource occupying the largest number of REs among M2 PUCCH resources; or the third resource is a PUCCH resource occupying the largest number of RBs from among the M2 PUCCH resources; or, the third resource is a PUCCH resource with the largest number of bits that can be carried in M2 PUCCH resources; wherein the M2 PUCCH resources are ones of the M PUCCH resources, and each of the M2 PUCCH resources and the first resource do not include the same OFDM symbol in a time domain, and M2 is a positive integer. In the scheme, all or part of the second UCI is carried by selecting one PUCCH resource occupying the maximum number of RBs or REs or capable of carrying the maximum number of bits, so that information in the second UCI is sent as much as possible, and the system performance can be improved.
It should be noted that, a part of the first UCI is carried on the first resource, which indicates that another part of the first UCI is not transmitted in the time unit n, or that another part of the first UCI may be discarded. A portion of the second UCI is carried on the third resource indicating that another portion of the second UCI is not transmitted within the time unit n or that another portion of the second UCI may be dropped.
There are a number of ways to select the portion to be transmitted. For example, the priority of the CSI may be based; or, the reference bit number according to the CSI; or, the selection is performed according to the number of REs or RBs occupied by PUCCH resources (configured by the first configuration information) corresponding to each CSI, or according to the ID number configured by the CSI. For example, the CSI included in the first UCI is selected to have a high priority, or the CSI included in the first UCI is selected to have a large number of reference bits.

This step is an optional step. The access network device and the terminal device may also determine the first configuration information in other manners, for example, the access network device and the terminal device determine the first configuration information through a preset setting.
As described above, the first configuration information may be transmitted through higher layer signaling.
The first configuration information is used for indicating reporting configuration of A CSI sent based on PUCCH resources. A is a positive integer greater than or equal to 1. Further, the first configuration information may also indicate a PUCCH resource-PUCCH on which the ith CSI reporting configuration of the a CSI reporting configurations is basedi.

Step 720: and the access network equipment sends second configuration information to the terminal equipment, wherein the second configuration information is used for indicating the M PUCCH resources. For example, the second configuration information is used to indicate resource information corresponding to M PUCCHs.
This step is an optional step. The access network device and the terminal device may also determine the second configuration information in other manners, for example, the access network device and the terminal device determine the second configuration information through a preset setting.
Alternatively, steps 710 and 720 may be one step, for example, the first configuration information and the second configuration information may be transmitted through one signaling. Alternatively, steps 710 and 720 may be two steps, for example, the first configuration information and the second configuration information may be separately transmitted through two signaling.
The M PUCCH resources may be, for example, M multi-CSI PUCCH resources. The multi-CSI PUCCH resource is configured to, when the terminal device needs to send L CSI in a certain time unit, where L > is L ' > (1), L and L ' are positive integers, and L is not 1, where L ' is carried by one of the M multi-CSI PUCCH resources.

The X PUCCH resources may be, for example, X PUCCH resource sets S1,…,SXEach PUCCH resource set comprises one or more PUCCH resources, and the number range of UCI bits supported by the ith PUCCH set is Li,1～Li,2And L isi,1＝Li-1,2. i is 1, …, X. UCI carried by X PUCCH resource sets comprises ACK/NACK information.
It should be noted that the first configuration information, the second configuration information, and the third configuration information may be sent by three signaling, two signaling, or one signaling.
Step 730: the terminal equipment and the network equipment respectively determine that at least two physical uplink control channel PUCCH resources conflict in a time unit n.
It should be noted that, the terminal device and the network device may determine that at least two physical uplink control channel PUCCH resources collide at the same time in time unit n, or may determine that the at least two physical uplink control channel PUCCH resources do not collide at the same time, which is not limited in this embodiment of the present invention.
Further, in the embodiment of the present invention, there may be multiple options for defining the PUCCH collision.
For example, when N > -2 PUCCH resources correspond to UCI that needs to be transmitted in the time unit N, it may be considered as PUCCH resource collision, and in this case, when N > -2 PUCCH resources are all resources corresponding to long PUCCH, it is considered that the two PUCCH resources collide regardless of whether the two PUCCH resources include the same OFDM symbol.
For another example, when N is 2 UCIs corresponding to PUCCH resources that need to be transmitted in the time unit N, and 2 PUCCH resources occupy at least one same OFDM symbol, the two PUCCH resources collide, and if the two PUCCH resources do not occupy the same OFDM symbol, the two PUCCH resources are considered not to collide.
For another example, when N > -3, as long as the UCI corresponding to the N PUCCH resources needs to be transmitted in time unit N, the N PUCCH resources may be considered to collide; and when the N is 2, judging whether PUCCH resource collision exists according to whether at least one same OFDM symbol is occupied.
For the terminal device and the network device, determining that at least three PUCCH resources are included in the time unit n includes:
according to configuration information reported by the periodic CSI (for example, information of a used PUCCH resource, and a period and time unit offset reported by the periodic CSI may be included), the terminal device or the network device determines whether there is a periodic CSI to be sent and a PUCCH resource configured for the periodic CSI to be sent in a time unit n;
the terminal equipment or the network equipment determines whether the ACK/NACK needing to be sent exists in the time unit n or not, and the PUCCH resources configured for the ACK/NACK needing to be sent exist.
In addition, the terminal device or the network device may determine whether there are SRs to be transmitted and PUCCH resources configured for the SRs to be transmitted in the time unit n according to the resource configuration information of the SRs, and the period and time unit offset reported by the SRs.
According to the above procedure, the PUCCH resources that should be originally transmitted in time unit n, that is, the number of PUCCH resources included in time unit n can be determined.
The configuration information may be the first configuration information sent in step 710 and/or the third configuration information sent in step 720 a.
The actions in this step may be implemented by the modem processor 404 of the terminal device 204 described above. The action in this step may be performed by the processor 301 of the access network device 202.
Step 740: the terminal equipment and the network equipment respectively determine a first resource and a third resource in a time unit n.
In a first alternative, determining the first resource of time unit n includes: determining that the at least PUCCH resource comprises at least one resource configured for HARQ-ACK information, and determining the one resource as the first resource, wherein the first UCI comprises the HARQ-ACK information. That is, if the UCI carried by the at least two PUCCH resources includes one resource includes HARQ-ACK information, the terminal device determines the one resource as the first resource.
In a first alternative, the manner of determining the one resource may be as described above, for example:
according to the total bit number of the first UCI needing to be transmitted in the time unit i, the PUCCH resource sets S are selected from the X PUCCH resource sets1,…,SXTo determine a set Sj；
Determining a set SjThe PUCCH resource x in (2), which is the first resource. For example, the terminal device determines from the DCIDefinite set SjPUCCH resource x in (2). And the access network equipment determines the PUCCH resource x according to the configuration information.
The M PUCCH resource sets are indicated by the second configuration information in step 720.
The optional mode maintains the original PUCCH resource to transmit the HARQ-ACK information as much as possible, thereby reducing the influence on the selection of the HARQ-ACK information resource caused by the collision of the HARQ-ACK information and the CSI and ensuring the transmission performance of the HARQ-ACK information.
In a second alternative, the determining the first resource includes:
determining that the at least two PUCCH resources comprise one resource configured for first CSI and one resource configured for second CSI, wherein the first resource is the resource configured for the first CSI, the first UCI comprises the first CSI, and the second UCI comprises the second CSI.

For example, in a second alternative, determining the first resource includes: and determining the PUCCH resource corresponding to the CSI with the largest transmission parameter as the first resource in the at least two PUCCH resources. Under the condition of permission, the PUCCH resources occupying the most resources are still continuously used, so that PUCCH waste caused by CSI collision can be reduced.
The reference bit number of the UCI may be an actual bit number of the UCI, or a maximum bit number of the UCI under a certain condition, or a bit number of the UCI under a certain parameter value. For example, if the UCI is CSI, the reference bit number of the CSI may be the maximum bit number of the CSI under all values of CRI/RI, or the reference bit number of the CSI is the CSI bit number under a certain predefined CRI/RI value, or the maximum bit number of the CSI within a certain value range of other measurement parameters. Others are not excluded.
Optionally, the transmission parameter of the first CSI is greater than the transmission parameter of the second CSI, where the transmission parameter is determined according to one or more of a reference bit number before coding, a reference bit number after coding, a priority of CSI, and a configuration index of CSI; or the resource parameter of the resource carrying the first CSI is larger than the resource parameter of the resource carrying the second CSI, wherein the resource parameter is determined according to one or more of the number of RBs occupied by PUCCH resources, the number of REs occupied by PUCCH resources, the number of OFDM symbols occupied by PUCCH resources, and the maximum number of bits carried by PUCCH resources.
Optionally, the transmission parameter of the first CSI is smaller than the transmission parameter of the second CSI, where the transmission parameter includes one or more of a reference bit number before coding, a reference bit number after coding, a priority of CSI, and a configuration index of CSI; or the resource parameter of the resource carrying the first CSI is smaller than the resource parameter of the resource carrying the second CSI, wherein the resource parameters include: one or more of the number of RBs occupied by the PUCCH resources, the number of REs occupied by the resources, the number of OFDM symbols occupied by the PUCCH resources and the maximum number of bits carried by the PUCCH resources.
Optionally, the transmission parameter of the first CSI is smaller than the transmission parameter of the second CSI, where the transmission parameter is determined according to one or more of a reference bit number before coding, a reference bit number after coding, a priority of CSI, and a configuration index of CSI; or the resource parameter of the resource carrying the first CSI is smaller than the resource parameter of the resource carrying the second CSI, wherein the resource parameter is based on the number of RBs occupied by PUCCH resources, the number of REs occupied by PUCCH resources, the number of OFDM symbols occupied by PUCCH resources, and the maximum ratio of PUCCH resource carrying
For example, in a second alternative, determining the first resource includes: and determining the PUCCH resource corresponding to the CSI with the minimum transmission parameter as the first resource in the at least two PUCCH resources.
It should be noted that the bearer described in the embodiment of the present invention is not necessarily actually used for sending UCI. There may be a resource originally configured for UCI, but not actually used, and the UCI is transmitted using a third resource.
Further, in an optional embodiment, determining a third resource in the time unit n includes: and determining a resource which does not comprise the same OFDM symbol with the first resource in the time domain in the M PUCCH resources as a third resource. For example, when only one PUCCH resource in the M PUCCH resources does not include the same OFDM symbol in the time domain as the first resource, the PUCCH resource is the third resource.
In another alternative embodiment, the determining the third resource in the time unit n includes:
step 7401 a: determining M3 PUCCH resources of the M PUCCH resources that do not include the same OFDM symbol in a time domain as the first resource, wherein M3 is a positive integer greater than 1.
Step 7402 a: and determining M1 PUCCH resources in the M3 PUCCH resources, wherein each resource of the M1 PUCCH resources meets the condition that the maximum bit number capable of being carried is larger than or equal to the sum of all bit numbers of the second UCI and the cyclic redundancy check bit number.

Figure BDA0001580157200000191
wherein M isRBNumber of RBs occupied in frequency domain for the PUCCH resource, NscNumber of subcarriers contained for each RB, NsymbThe number of OFDM symbols, Q, occupied by the PUCCH resource in the time domainmModulation order, r, used for CSI on the PUCCH resource from transmissionmaxAnd coding the maximum allowable channel code rate for the PUCCH resource. These parameters may be configured by the base station for each multi-CSI PUCCH resource, for example, included in the second configuration information. O isUCI-iThe reference bit number of the ith UCI is, i belongs to Lambda to indicate that the ith UCI belongs to the second UCI, OCRCIs the number of bits of the CRC.
When M1 is equal to 1, the M1 PUCCH resources are the third resource, and step 7403a is not executed again. When M1 is greater than 1, step 7403a is also performed.
Step 7403 a: of the M1 PUCCH resources, one PUCCH resource that occupies the smallest number of REs or RBs is determined to be the third resource.
In another alternative embodiment, the determining the third resource in the time unit n includes:
step 7401 b: determining M2 PUCCH resources of the M PUCCH resources not including the same OFDM symbol in a time domain as the first resource, wherein M2 is a positive integer.
Step 7402 b: determining that no resource with the maximum bit number capable of being carried being greater than or equal to the sum of all bit numbers of the second UCI and the cyclic redundancy check bit number exists in the M2 PUCCH resources.
Step 7403 b: determining, as the third resource, a resource satisfying the following condition among the M2 PUCCH resources:
the PUCCH resources occupying the largest number of REs in the M2 PUCCH resources; alternatively, the first and second electrodes may be,
the PUCCH resource occupying the largest number of RBs in the M2 PUCCH resources; alternatively, the first and second electrodes may be,
and the PUCCH resource with the maximum number of bits capable of being carried in the M2 PUCCH resources.
In another alternative embodiment, the determining the third resource in the time unit n includes:

step 7402 c: and determining whether the M3 PUCCH resources exist and satisfy that the maximum number of bits that can be carried is greater than or equal to the sum of all the bits of the second UCI and the cyclic redundancy check (crc) bits, if M1 PUCCH resources exist and satisfy the condition, and if M1 is equal to 1, determining that the M1 PUCCH resources are the third PUCCH resources, and performing step 750. When M1 is greater than 1, step 7403c is performed. When there are no resources satisfying the condition, perform step 7404 d;
step 7403 c: of the M1 PUCCH resources, the PUCCH resource with the smallest number of occupied REs or RBs is determined to be the third resource, and step 750 is executed.

The actions in this step may be implemented by the modem processor 404 of the terminal device 204 described above. The action in this step may be performed by the processor 301 of the access network device 202.
It should be noted that, if the third resource that satisfies the above condition is not found according to the above method, for example, each of the M PUCCH resources includes a resource that includes the same OFDM symbol as the first resource in the time domain, step 740 only determines the fourth resource, without using the first resource.
In an alternative embodiment, for example, in the case that the first UCI includes the first CSI and the second UCI includes the second CSI, the determining the fourth resource may include: determining a fourth resource from the M multi-CSI PUCCH resources (i.e., the M PUCCH resources in the foregoing) corresponding to the second configuration information, where the fourth resource is one PUCCH resource occupying the smallest number of REs (or number of RBs or the largest number of bits that can be carried), and simultaneously satisfying that the PUCCH resource can carry the first UCI and the second UCI at an actual code rate that does not exceed the maximum coding code rate. That is, the first UCI and the second UCI are both transmitted using the fourth resource. If no PUCCH resource capable of carrying all the first UCI and the second UCI exists in the M multi-CSI PUCCHs, the PUCCH resource with the largest RB number is selected, and N2< N UCIs are selected to be carried on the PUCCH resource according to a predefined rule. Of course, this alternative embodiment is not limited to the above case.
In another alternative embodiment, for example, in the case that the first UCI includes HACK-ACK information and the second UCI includes CSI, the determining the fourth resource may include: according to the bit number of N1 ACK/NACK and the reference bit number of N2 CSI (or according to the total bit number of all N second UCIs), determining one resource set j in X PUCCH resource sets, and selecting a fourth resource from the set j according to the indication information of the DCI corresponding to the N1 ACK/NACK. The fourth resource is used to carry all ACK/NACK and N4 ═ N2 CSI, and the determination method of all or part of UCI in other UCI is determined by the maximum code rate of the fourth resource, which is similar to the above embodiments and is not described again here.
Step 750: and the terminal equipment transmits part or all of the first UCI on a first resource in a time unit n, and transmits part or all of the second UCI on a third resource in the time unit n.
Of course, if there is no third resource satisfying the condition, the terminal device transmits part or all of the first UCI and the second UCI at the fourth resource within the time unit n.
Further, when parts of the first UCI are transmitted, how to select which part of the first UCI is transmitted or discarded may be implemented according to predefined rules. For example, according to the priorities of different parameters in the UCI, the parameters with lower priorities are preferentially discarded until the first resource can carry the parameters that are not discarded with a code rate that does not exceed the maximum coding code rate. The same is true for the portion of the second UCI being sent.
The operation in this step may be implemented by the transceiver 401 of the terminal device 204, or may be implemented by the modem processor 404 of the terminal device 204 and the transceiver 401 together.
Step 760: the access network equipment receives part or all of the first UCI on a first resource in a time unit n, and receives part or all of the second UCI on a third resource in the time unit n.
Of course, if there is no third resource satisfying the condition, the access network device receives part or all of the first UCI and the second UCI at a fourth resource within the time unit n.
The action in this step may be implemented by the transceiver 302 of the access network device 202, or may be implemented by the processor 301 and the transceiver 302 of the access network device 202 together.
